Особенности низкотемпературного магнитосопротивления монокристаллов вольфрама

Abstract

Static skin effect, i.e a concetration of dc-current near sample surface, occurs due to strong electron-surface scattering in pure tungsten single crystals at high magnetic fields. At these conditions, the magnetoresistivity is very sensitive the magnitude and direction of ex-ternal magnetic field. In particular, a form of angular dependence of resistivity is mainly determined by a conductor shape at 4.2K. The observed effects can be used for development of cryogenic sensors of magnitude and angular displacements of magnetic field.
